+* 70 cm lining fabric (e.g. ripstop nylon or uncoated, lightweight + cordura); +* two pieces of rigid padding about 30 cm × 42 cm: a rigid foam, or a + rigid sheet plus softer foam +* 2 meters 2.5 cm webbing; +* 7 meters twill webbing to bind the raw edges: +* 1 meter waterproof zipper plus sliders etc (to make a 90 cm long + zipper); +* 33 cm round or thin elastic; +* 1 handle or 25 cm 2.5 cm webbing; +* termoplastic sewable feet; +* 2 ladderlocks; +* heavyweight sewing thread (regular all purpose thread isn't strong + enough). + +Pattern +------- + +The pattern is available in the following formats: + +:download:`modular_front_pack.val.val` + valentina file where the measurements can be customized; +:download:`modular_front_pack-copyshop.pdf` + A0 PDF file for copyshop printing; +:download:`modular_front_pack-A4.pdf` + A4 tiled PDF file for home printing. + +the latter two formats are based on a finished measurement of 30 cm × 42 +cm × 5 cm (width × height × depth) with 1.2 cm for the zipper. + +Instructions +------------ + +.. tip:: + + Any time coated / water resistant fabric is involved, only use pins in + the sewing allowance, and use a long seam (e.g. 4 mm) to minimize holes + in the coating and preserve the water resistance. + Binder clips are useful to keep things together while sewing, and so is + masking tape, depending on the cases. + In the pictures you can see what I used in most cases. + +.. tip:: + + When working with webbing and edgebinding measure the amount you need, + cut and seal the edges with a flame to prevent fraying. + +.. tip:: + + When sewing TPU-coated fabric sometimes the machine may have issues + carrying it; in that case put a piece of tissue paper on the coating + while sewing and rip it out afterwards. + +Cut all fabric and lining parts according to the pattern, using the +given sewing allowance (usually 2 cm). +Cut the rigid padding about 5 mm smaller than the pattern. + +MOLLE panels +^^^^^^^^^^^^ + +Cut two extra front / back panels from the outer fabric; use either + +Print either the full pattern for a back panel with MOLLE slots, +:download:`molle_pattern_panel.svg` or the version on just one A4 sheet +:download:`molle_pattern_a4.svg`. + +Cut two extra front / back panels, and cut the MOLLE slots on it with a +knife, optionally cutting the rounded edges with a punch. + +Heat-seal each edge with a hot hair station set at ?°C or a lighter +flame. + +Sew the panels to the main front / back panels on the marked vertical +lines. + +From now on, treat as one. + +Lining Pieces +^^^^^^^^^^^^^ + +Take the inner pocket lining piece, zigzag the top edge, fold it down 1 +cm and again 2 cm, sew 1-2 mm from the bottom fold to create a channel +for the elastic. + +Place the elastic in the casing, put the wrong side of the pocket on the +right side of the back panel lining with a pleat at the center bottom, +sew all around with a seaming allowance of 1.5 cm, backticking over the +elastic. + +Sides and Zipper +^^^^^^^^^^^^^^^^ + +Place the right side of the zipper on the right side of the sides place +the right side of its lining on top of both; sew so that the zipper is +sandwiched between the two layers and turn them inside out so that the +zipper protudes. + +Insert the zipper pulls in the assembled top/sides. + +Baste the lining +^^^^^^^^^^^^^^^^ + +In this step we will attach all lining pieces to their fabric ones, +wrong sides facing with a wide zig-zag stitch, so that they are easier +to treat them as one while assembling the backpack and to prevent the +raw edges from fraying before they are covered with tape. + +Sew the lining and fabric of the top/side panels on the remaining raw +edges. + +Sew the lining to fabric of the bottom panel. + +Sandwitch the rigid padding between the lining and the fabric of the +front panel, sew all around the edges. + +Sandwitch the rigid padding between the lining (including the pocket) +and the fabric of the back panel, sew all around the edges. + +Shoulder straps +^^^^^^^^^^^^^^^ + +Sew two pieces of webbing 45 cm long to the sewing allowance at the top +of the back panel, aligned with the MOLLE pattern. + +Cut two pieces of webbing 70 cm long, seal their edges. + +Put one end on the right side of one small triangle of fabric, so that +one edge goes from one corner to the middle of the long side, and there +are 5 cm of webbing beyond the long side. + +Fold the triangle in half, right sides facing, and sew 2.5 cm from the +long edge. + +Turn the triangle inside out, topstitch near the edges of the webbing. + +Sew the lower strap triangles to the bottom of the sides of the back +panel, just above the rounded off corner with a 1.5 cm allowance. + +Assemble the backpack +^^^^^^^^^^^^^^^^^^^^^ + +Place the bottom panel on the top/side panel, right (fabric) sides +facing, sew on both short edges. Press the raw edges towards the +bottom and bind them with twill webbing. + +Place the right (fabric) side of the top/bottom/sides on the right side +of the back, sew all around. You may have to clip the raw edges near the +curves before sewing. + +Open a few centimeters of the zipper. + +Place the right (fabric) side of the top/bottom/sides on the right side +of the front, sew all around. As above if needed clip the raw edges +before sewing. + +Bind the remaining raw edges with the twill webbing (this will require +two pieces of twill webbing 157 cm long). + +Turn the finished backpack inside-out and enjoy it. diff --git a/source/accessories/bags/modular_front_pack/molle_pattern_front_back_panel.svg b/source/accessories/bags/modular_front_pack/molle_pattern_front_back_panel.svg new file mode 100644 index 0000000..c373177 --- /dev/null +++ b/source/accessories/bags/modular_front_pack/molle_pattern_front_back_panel.svg @@ -0,0 +1,376 @@ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + -- cgit v1.2.3
